Sneaker wave warning today, Wednesday

The National Weather Service is warning North Coast residents about a sneaker wave threat today and Wednesday due to long period waves on the coast.

A storm in the central Pacific has generated significant waves that started to impact the coastline this afternoon, with breakers up to eight feet and periods near 20 seconds. According to the weather service, the large waves can surprise beachgoers by causing a high volume of water to run up the beach, hitting sections not previous reached. With high velocities and large volumes of water, the wave can easily knock down adults and children, then drag them into the sea as the water retreats. Water temperatures in the low 50s make survival difficult once in the ocean. Waves will build to greater heights on Wednesday, continuing the threat.

The weather service is warning residents to stay away from the edge of the water and never turn their back on the ocean. If witnessing someone in distress, call 911.
